ARMATURE-WINDING MACHINE.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed June 15, 1905. Serial No. 265,339.

To all whom it may concern:

Be it known that I, CnARLEs H. LEWIS, of the city and county of New Haven and State of Connecticut, have invented new and useful Improvements in Armature Winding Machines, of which the following is a full, clear, and exact description, when taken in connection with the accompanying drawings, which form a part thereof, and in which- Figure 1 represents a front elevation (partly broken away) of the main portion of a winding machine embodying the invention, Fig. 2, a plan view of the same, and a portion of the guiding and tension device, Fig. 3, a central longitudinal vertical section through one of the armatures and the associated parts of the machine, Fig. 4, a side elevation (partly in section) of the guiding and tension devices, Fig. 5, a side elevation of one of the armature holders and one of the brackets of the machine, Fig. 6, a similar view of the bracket alone, Fig. 7, a reverse view of the armature holder, Fig. .8, an end elevation of r a part of the tension pulley and associated parts of the tension device, Fig. 9, a transverse horizontal section on line 9-9 of Fig. 8, and Fig. 10, a central longitudinal section through the handle of the guiding mechanism.

In all figures, s milar letters of reference represent like parts.

This invention relates to machines for winding wire on armatures, and has for one of its objects the production of a machine by which a plurality of armatures may be wound simultaneously, and in which the wire is guided and the tension regulated automaticall To this and other ends, the invention consists of the several improvements and combinations of parts set forth and claimed hereinafter.

For a more particular description of the invention reference is had to the accompanying drawings, lI1-Wl1lClP the parts designated by the letter A represent armatures and B the wire or Wiresbemg wound thereon. Each of the armatures A is held between a pair ,of

blocks or holders O and F, having substan tially rectangular concavities or de resslons D, into which the side plates Eoi' t ie armatures are adapted to lit snugly, as shown more particularly in Figs. 3 and. 5, so that on 4 pair.

the rotation of the armature holders (land F, the armature A is rotated therewith.

The end holder F of the series is shown provided with a tapering shaft or spindle G,

adapted tobe forced home into a socket H in a rotary shaft I, shown driven by the pulley J. The intermediate holders C are rigidly I mounted on short shafts or spindles K, which N, within a stationary bracket 0. Each bracket O is provided with one or more projections P, and is held from rotation by means of rods or wires Q, which extend through perforations in the projections P, and terminate in a rigid support R. The brackets O are thus supported on the rods Q, and are prevented thereby from rotary movement, but are capable of longitudinal sliding movement on the rods. Coiled springs S are mounted on the rods between adjacent brackets and tend to' force the brackets apart. Each armature is held in place by being gripped by two holders C, and the series of armatures is held by'locking the end holders so that the brackets cannot spread apart- When, however, it is desired to remove the armatures it is only necessary to remove one of the end holders, whereupon the springsS will force the brackets apart and separate each pair of holders, so that the armature carried thereby may be removed.

The IOtfiIfYlIlOVGIIlGIlt of the shaft I is cominunicated to each armature by means of the spindle G and end holder F, through the armature A, to the other holder C of the first As each holder C is rigidly connected to the adacent holder of the nextpair on the opposite side of its supporting bracket, the rotary movement of each of these holders is communicated to the next adjacent holder.

The wire B for each of the armatures passes over one pulley T from under another pulley U, mounted on a support V, pivotally secured to an upright W. A series of these uprights W and'pulleys are mounted on a sleeve X at. distances corresponding to the relative distances between the armatures. The sleeve Y is loosely mounted on a stationary shaft Z, and is provided with two arms A and B, having at their ends teeth adapted the pulley J. The thread on the shaft C is divided, as shown in Fig. 2, and one part is a left hand screw, and the other a right hand screw. One arm, as A, is adapted to engage one of the portions of this thread, and B to engage the other portion. The arms extend, as shown in Fig. 4, on opposite sides of the shaft 0, and their ends are further apart than the diameter of the threaded shaft 0. By this construction, only one of these arms will engage the shaft at the same time, and both may be removed simultaneously if desired. A lever F is rigidly connected to the sleeve Y to rotate the sleeve to engage one arm and release the other from engagement with the shaft C when desired. The. end of the lever F projects into the hollow' interior G of a handle H. A coiled spring I in the interior G bears at one end against the handle H and at the other end against a washer J rigidly mounted on the lever F The handle H is provided with twostudsK and L, one shown above and one below the lever F. VVhenone of these studs, as K, engages a bracket M (Figs. 2 and 4), the lever F and sleeve Y are swung so that the arm A engages the screw C. When it'is desired to engage the other arm B, the handle H is drawn outward against the tension of the spring I, so that the lug K is disengaged from the bracket M.

The lever and handle are then forced downward, and the lug L adapted to engage the under side of the bracket M, in which position the sleeve Y will have been rotated sufficiently to bring the arm B into engagement with the screw threaded shaft C. The wire B before passing to the pulleys U and T from the spool N passes over a tension pulley O, mounted on a post I (Fig. 9) on which are screwed two blocks or disks Q one of which has two slots S for two parallel vertical Wires R, so that the pulley O and its ost P are slidably mounted on the wires A s ring T engages one of the blocks Q and the head V of the wires R and constantly I tends to yieldingly draw the pulley Oupare drawn oil the spools over the tension ulley 0 under and over the pulleys U and f. and wound around the armatures. In order that the wire may be wound neatly and accurately, a lateral movementi of the pulleys U and T is effected by means of the sleeve Y, which. as has been pointed out, is

movement of the guide loosely mounted on the shaft Z. When, for example, the uppxer arm A of the sleeve Y is engaged with t e screw threaded rotary shaft C, the sleeve Y slowly travels toward the left and the 'wire 'wound, as suggested in Fig. 2. When the wire is wound in one layer around the armature, the operator disengages the handle H and swings the lever F so that the other'arm B" of the sleeve Y engages the screw threaded rotary shaft 0, whereupon the sleeve Y will travel in the opposite direction. As all the wires for the armatures pass over pulleys U and T mounted on supports on the sleeve, the lateral adjustment of all the wires is simultaneous.

, If it is desiredto stop the lateral movement of the guiding ulleys .U and T, although the rotation of the armature is continued, the lug K or L is disengaged and the lever F swung to a osition where neither of the arms A or screw threaded shaft C This wil obviate any movement of sleeve Y and thelateral' ulleys U and T. Upon the completion of t e winding of the armature, the machine is stopped and the wires severed. One of the end armature holders F isyloosened, whereupon the springs S will tend to separate the brackets O and armature holders 0 to release the wound armature.
